pedunculo longioribus erumpente, scpalis linearibus petjxlisqxie lineari- 

 lanceolatis acuminatissimis, labello obovato acuminato oonvexo integer- 



rimo basi unicalloso. Brazil. This has the habit and sweet odour 



of E. f'ragrans, from which it differs in the colour of its flowers, in the 

 long tapering figure of the flower-buds, which is caused by the pecuhar 

 form of the sepals and petals, and in the shape of the labellum, which 

 is convex not concave, obovate, and delicately striped with pink at 

 its base.

 oblongo acuminato basi convexo ecalloso, colmnna obtus^ S-dentatu, 



antherae cardinis appendice oblonga denticulata. Brazil. Nearly 



related to E. fragrans. The flowers are straw-coloured, with a few purple 

 streaks on the column and at the base of the lip, and have a heavy not 

 very pleasant smell, something Uke that of Ground-ivy {Glechoma).

 vissimo acuto intus sub columna pubescente : callo baseos concavo car- 



noso, dente columnse postico obtuso. Brazil, Peru. A variable 



plant, readily known by its very short lip, on the base of which is placed 

 a large concave caUus, which presses against the column and gives the 

 lip the appearance of being divided horizontally into two layers. On 

 very strong specimens there are oceasionally three or four leaves on a 

 pseudobulb.
